Definitions

  • the invention relates to a spherical plain bearing preferably for chassis components of motor vehicles with the generic features mentioned in the preamble of claim 1.
  • the spherical bearings described there are preferably used in chassis modules for commercial vehicles. Such bearings have proven themselves in principle in the prior art. Under normal operating conditions, radial, axial and caroisic movements of the inner part relative to the housing are achieved by molecular deformations of the elastomer body which is under axial prestress.
  • the preload is brought about during assembly of the spherical bearing by inserting the inner part with the elastomer body adhering to it and adhering axially arranged bearing shells designed as stop rings into the housing, then the elastomer body, preferably using a press over the stop rings onto a defined dimension compressed and at the same time the spring retaining ring is inserted into the radial recess of the interior of the joint housing, the opposite stop rings resting on a shoulder screwed into the housing, so that the elastomer body can no longer be relaxed or only slightly.
  • the object of the present invention is therefore to develop a spherical plain bearing of the generic type described so that even under extreme operating conditions, the reliable functioning of the spherical plain bearing is ensured by ensuring that the locking ring used, which is a cost-effective and simple preload of the elastomer body Spherical bearing represents, at any time remains in the position determined during the assembly.
  • the stop ring of the elastomer body cooperating with the spring retaining ring has, in its axial outer side facing the spring retaining ring, a radially circumferential recess on the outer edge of the stop ring, into which the spring retaining ring engages when the joint bearing is in the assembled state.
  • This combination of features according to the invention reliably prevents the spring retaining ring from jumping out of the recess in the joint housing due to radial deformation of the spring retaining ring.
  • the depth of the recess in the axial direction of the spherical plain bearing is about half the thickness of the spring retaining ring used.
  • Figure 1 is a half-sectional view through a joint bearing according to the invention.
  • FIG. 2 shows an enlarged illustration of detail A from FIG. 1.
  • the spherical plain bearing consists of an inner part 1 which has fastening pins 2 and 3 on both free ends for connection to a motor vehicle part.
  • the central, spherical central region 4 of the inner part 1 is enclosed by an elastomer body 5, which is firmly adhered to the inner part 1, for example by a vulcanization process.
  • Stop rings 6 and 7 are respectively arranged on the end faces of the elastomer body 5 seen in the axial longitudinal direction of the spherical plain bearing and are firmly connected to the elastomer body.
  • the elastomer body 5 is accommodated together with the stop rings 6 and 7 in an articulated housing 8 which is essentially tubular and forms a cylindrical interior 9.
  • the cylindrical interior 9 is provided on one side with a circumferential shoulder 10 against which the stop ring 7 is supported.
  • the other stop ring 6 is supported in the assembled state of the spherical bearing against a spring retaining ring 11 which is inserted in a circumferential radial recess 12 of the interior of the joint housing.
  • the depression is designed as a U-shaped groove.
  • the elastomer body 5 In the unmounted state, the elastomer body 5 has a greater width in the axial longitudinal direction than that which is given between the inside of the shoulder 10 and the inside of the spring retaining ring 11 within the joint housing 8.
  • the spherical plain bearing according to the invention has the detail drawing shown in FIG. 2 A special feature shown in Figure 1.
  • FIG. 2 shows the fastening area of the elastomer body 5 with the adjacent stop ring 6 through the spring retaining ring 11, which is received in the recess 12 of the joint housing 8.
  • the technical teaching according to the invention provides that the stop ring 6 which interacts with the spring locking ring 11 has a recess 14 on its axial outer side 13 which faces the spring locking ring. This recess is arranged circumferentially on the outer edge of the stop ring 6 and has an essentially rectangular cross section.
  • the radial boundary surface 15 is dimensioned in such a way that it is only insignificantly smaller than the smallest inner diameter of the spring retaining ring 11.
  • FIG. 2 also shows that the dimension T, which denotes the depth of the recess 14, is essentially half the thickness S of the spring retaining ring 11.
  • the geometric design and the dimensions of the recess 14 ensure that after insertion of the spring retaining ring 11, the latter cannot be snapped out of the recess 12 as a result of dynamic loads.

Abstract

L'invention concerne une articulation à rotule destinée de préférence à des éléments de châssis de véhicules automobiles et comprenant un boîtier d'articulation tubulaire (8) qui forme un espace intérieur cylindrique et dans lequel sont logés une partie intérieure métallique (1) et un corps élastomère (5) entourant la partie intérieure (1) en y adhérant. Le corps élastomère (5) est précontraint axialement dans le sens longitudinal axial de l'articulation à rotule, avec intercalation d'anneaux de butée (6, 7) réalisés sous forme de coquilles de coussinet et reliés de manière fixe au corps élastomère, qui coopèrent avec des parties correspondantes (10) faisant saillie dans l'espace intérieur du boîtier d'articulation (8). Au moins une des parties en saillie est formée par un anneau à rondelle-ressort d'arrêt (11) qui est inséré dans un évidement radial (12) de l'espace intérieur du boîtier d'articulation (8) et dont la face latérale orientée vers le centre de l'espace intérieur s'appuie sur l'une des faces extérieures axiales (13) d'un anneau de butée. Selon l'invention, l'anneau de butée (6) coopérant avec l'anneau à rondelle-ressort d'arrêt (11) présente, dans sa face extérieure axiale (13) orientée vers l'anneau à rondelle-ressort d'arrêt (11), un évidement (14) s'étendant radialement sur l'arête extérieure de l'anneau de butée (6) et dans lequel l'anneau à rondelle-ressort d'arrêt (11) s'engrène à l'état monté de l'articulation à rotule. Grâce à cette configuration, l'anneau à rondelle-ressort d'arrêt reste dans sa position prédéfinie, même en cas de contraintes dynamiques importantes sur l'articulation à rotule.
